Abstract

SNG (solidified natural gas) technology is a promising and potential technology for long-term and large-scale storage of methane in hydrates due to the plethora of benefits it offers in comparison to conventional methods of storage. In this study, we aim to investigate the kinetics of mixed hydrate formation using a ternary C1(93%)-C2 (5%)-C3 (2%) gas mixture representing the natural gas. The main objective is to study the effect of presence of higher hydrocarbons (ethane and propane) in influencing the mixed hydrate formation kinetics with the additional presence of thermodynamic promoter, tetrahydrofuran.
Experiments to study the effect of temperature and pressure on the mixed hydrate formation kinetics in an unstirred reactor configuration were performed. Results from this study will provide salient information in order to advance the SNG technology towards commercial implementation.
